For every outcome, experience, there are associated variables which are directly tied to the outcome by simultaneously being a part of it and the cause of it. For example, for an illness to arise, your life experience must be harmonized with the illness to an extent and thus there must be variables, causative factors, representing this harmony in the form of objects and actions, experiences which are both a part of the experience of having the illness and the cause of it.
Therefore, by removing these variables, the harmony with the illness is removed and thus so is the experience of illness. This is true for all experiences too. By adding variables that are harmonized with your desires to your life experience and by removing disharmonious variables, harmony with your desires will be achieved and they will manifest to a greater and greater degree with the introduction of each additional harmonious variable.
